T-Mobile VPN problems related to IPv6 network.

Aug. 28, 2021, 5:35 a.m.

Some of our T-Mobile users have reported problems using tcp_trick or Polycentric mode of SmokeV2 VPN protocol.

The problem might be due to the way iPv6 is implemented on T-Mobile and iOS altogether, Our team is working on debugging this issue by replicating the T-Mobile IPv6 network. However, for the time being, you can use all other SmokeV2 modes normally by following steps on your iPhone or iPad device.


-> Start bVPN app.

-> Select SmokeV2 on the top left of the connection screen.

-> Tap on Settings.

-> Under Tcp_trick settings tap Off.
